But the child's parents say he had no underlying medical conditions. The case points out the fact that there are still mysteries surrounding the new virus.

"Information is changing all the time," said Dr. McGaha. "It is a new virus. It is affecting different populations. We are hearing new information from media sources."

Dr. McGaha with the Texas Health Department says new information comes out weekly.

"CDC and the state health department look at all those studies that have been done for H1N1 and compile them all together and analyze them and see which have the most scientific validity," said Dr. McGaha.

Case and point: A study released last week says people only need one dose of the vaccine now instead of two.

"We will have to wait and see how it plays out," said Dr. McGaha.

And, more new research released Monday says people infected with H1N1 may be contagious longer than previously thought. But, like many new studies, the CCD has not confirmed this one yet.
